Medium-voltage cable joint
A kit for joining opposing ends of two medium-voltage (between about 3.3 kV and about 52 kV) electrical power distribution cables, comprising an electrically-conductive connector for connecting the conductors of the cables, an electrically-insulating surround material for enveloping the connector, a partial discharge detector, comprising a generally cylindrical, electrically-conductive sheath around the insulating surround, from which an electrically-conductive element extends in an axial direction along the length of at least one of the cables, an outer protective tube for surrounding the remainder of the kit, wherein the conductive element is sufficiently long to project out of the protective tube. A partial discharge detector and a medium voltage cable run are also described.

WATER-RESISTANT ELEMENT, EXTERNAL CONNECTION WIRE MODULE, ANTENNA BOX MODULE AND METHOD OF FIXING A WATER-RESISTANT ELEMENT AT A HOUSING
A water-resistant element, adapted to an opening, comprising a deformable body, a first plate and a second plate is provided. The first plate is disposed at and against a first side of the deformable body. The second plate is disposed at and against a second side of the deformable body. When the deformable body is disposed in the opening, a relative displacement between the first plate and the second plate is used to change a shape of the deformable body such that the deformable body closely fits the opening in order to block moisture from entering into the opening. In addition, an external connection wire module comprising the water-resistant element, an antenna box module comprising the external connection wire module and a method of fixing the water-resistant element at a housing are also provided.
Partly Pre-Assembled Cable Joint
A cable joint includes a cable joint body, a conductive connector disposed within the cable joint body and electrically connecting a first cable to a second cable, and a first conductive element electrically connecting a first shielding layer of the first cable to a second shielding layer of the second cable. The cable joint body includes a first insulating sleeve and a re-jacketing sleeve at least partly encompassing the first insulating sleeve. The re-jacketing sleeve forms a channel along a longitudinal axis of the first insulating sleeve. The first conductive element is disposed within the channel. The channel is collapsed after heat shrinking the first insulating sleeve and the re-jacketing sleeve.

SPLICED SHIELDED WIRE CABLE AND METHOD OF MANUFACTURING SAME
A wire harness assembly including a first, second, and third shielded wire cable, each having a core conductor surrounded by a shield conductor which is surrounded by a insulative jacket. Portions of the core conductors are sonically welded to one another. The assembly also includes a flexible insulative layer wrapped about the sonically welded core portions, a flexible conductive layer wrapped about the flexible insulative layer and exposed shield portions, and a section of heat shrink tubing in which the flexible conductive layer and portions of the insulative jackets are enclosed.

Method in the manufacturing of an insulated electric high voltage DC termination or joint
A method in the manufacturing of an insulated electric high voltage DC termination or joint includes providing an insulated electric high voltage DC cable including a high voltage DC conductor, a polymer based insulation system surrounding the high voltage DC conductor, the polymer based insulation system including an insulation layer and a semiconducting layer surrounding the insulation layer, and a grounding layer surrounding the semiconducting layer; removing the grounding layer and the semiconducting layer in at least one end portion of the high voltage DC cable, mounting a field grading adapter or joint body in the at least one end portion of the high voltage DC cable; and subjecting the insulation layer of the polymer based insulation system in the at least one end portion of the high voltage DC cable for a heat treatment procedure, while being covered by the mounted field grading adapter or joint body.
Cable Connector
A cable has a corrugated armor exterior surface, and a split bushing defines an interior surface which conforms to the corrugated exterior surface. The bushing is split radially in one place to form a gap which may be opened to allow the bushing to open, or the bushing is split radially at two or more places to form two or more parts, and is fitted about the corrugated exterior surface. The bushing defines first and second external chamfer surfaces. A connector includes a body having external threads and a chamfer which urges against the first bushing chamfer. A nut has internal threads which engage the external threads of the body, and a chamfer which urges against the second bushing chamfer. As the nut is tightened onto the body, wedge action on the first and second bushing chamfers compresses the bushing around the corrugated exterior surface to secure the connector to the cable.
Underwater electrical connection system
An undersea connection system for connecting together at least three high voltage or very high voltage undersea electric cables comprises an outer cage defining a connection space; and a connection fitting comprising a conductive connection electrode that presents a junction node from which there extend at least three branches. Each of the at least three branches of the conductive electrode includes a male terminal portion that is connected to a respective one of the electric cables in a connection zone about which there is mounted a connection sleeve made of pre-molded insulating material that receives, via its ends, firstly the male terminal portion of one of the branches of the conductive electrode, and secondly the connection end of one of the electric cables.
